Single AZ MySql RDS Database Instance is not pingable!

I have a single AZ MySql RDS Database instance in a private subnet and EC2 instances in different private subnets. Security Group attached to RDS instance is allowing all inbound ICMP traffic and Security group attached to EC2 instances allowing all outbound traffic then can we ping rds instance from EC2 instances either through its respective private ip or dns name?

Hello,

Amazon RDS doesn't accept internet control message protocol (ICMP) traffic, including ping.

You can use Netcat to test the connectivity to RDS database,

nc -zv DB-instance-endpoint port
